A siv - Case qauv yog a qauv ntawm qhov sib txawv ntawm cov neeg siv cuam tshuam nrog lub system los daws qhov teeb meem. Qhov tseem ceeb tshaj plaws qauv cov ntsiab lus yog: siv li cas , actors thiab kev sib raug zoo ntawm lawv. A siv - cas daim duab yog siv graphically depict ib subset ntawm cov qauv kom yooj yim rau kev sib txuas lus.
Hais txog qhov no, lub hom phiaj tseem ceeb ntawm kev siv rooj plaub qauv yog dab tsi?
Lub hom phiaj ntawm Kev Siv Case Diagrams Cov lub hom phiaj ntawm kev siv case diagram yog mus ntes lub dynamic nam ntawm ib tug system. Txawm li cas los xij, qhov no txhais yog generic dhau los piav txog lub hom phiaj , raws li lwm yam plaub daim duab (kev ua, ntu ntu, kev sib koom tes, thiab Statechart) kuj muaj tib yam lub hom phiaj.
Ib yam li ntawd, koj yuav ua li cas thiaj tsim tau ib qho qauv siv?
- Txheeb xyuas Cov Neeg Ua Haujlwm (lub luag haujlwm ntawm cov neeg siv) ntawm qhov system.
- Rau txhua pawg ntawm cov neeg siv, txheeb xyuas txhua lub luag haujlwm ua los ntawm cov neeg siv cuam tshuam rau lub system.
- Txheeb xyuas dab tsi yog cov neeg siv yuav tsum tau ua kom ua tiav cov hom phiaj no.
- Tsim cov ntaub ntawv siv rau txhua lub hom phiaj.
- Txhim kho cov teeb meem siv.
Tsuas yog li ntawd, qhov kev piav qhia ntawm kev siv yog dab tsi?
A siv li cas yog sau piav qhia ntawm seb cov neeg siv yuav ua li cas hauv koj lub vev xaib. Nws qhia txog, los ntawm tus neeg siv qhov kev xav, lub kaw lus tus cwj pwm raws li nws teb rau qhov kev thov. Txhua siv li cas yog sawv cev raws li ib theem ntawm cov kauj ruam yooj yim, pib nrog tus neeg siv lub hom phiaj thiab xaus thaum lub hom phiaj ntawd tiav.
Dab tsi yog qhov sib txawv ntawm kev siv rooj plaub?
Yeej muaj ob hom kev siv rooj plaub cov kws tshuaj ntsuam tuaj yeem kos los ntawm: Kev Lag Luam Siv Cases thiab System Siv Cases . Kev lag luam Siv Cases muaj ntau ntxiv txog qhov uas tus neeg siv xav tau los ntawm qhov system thaum System Siv Cases muaj ntau ntxiv txog qhov system ua li cas. Ob leeg siv hom ntawv tuaj yeem sawv cev los ntawm daim duab lossis ntawv.
Pom zoo:
Dab tsi ntawm cov hauv qab no yog qhov zoo ntawm kev siv cov khoom siv pom kev hauv kev hais lus?
Qhov txiaj ntsig tseem ceeb ntawm kev siv cov khoom siv pom hauv koj cov lus hais yog tias lawv ua kom cov neeg tuaj saib muaj kev txaus siab, hloov kev mloog ntawm tus neeg hais lus, thiab ua rau tus neeg hais lus muaj kev ntseeg siab ntau dua hauv kev nthuav qhia tag nrho
Dab tsi yog qhov sib txawv loj ntawm kev txheeb xyuas qhov yuam kev thiab kev kho cov lej yuam kev?
Ob qhov kev tshawb nrhiav qhov yuam kev thiab kev kho qhov yuam kev yuav tsum muaj qee qhov ntawm cov ntaub ntawv rov qab xa mus nrog cov ntaub ntawv tiag tiag; kev kho yuav tsum muaj ntau tshaj li kev tshawb nrhiav. Parity bits yog ib txoj hauv kev yooj yim rau kev tshawb nrhiav qhov yuam kev. Ib qho parity me ntsis yog ib qho ntxiv me ntsis xa nrog cov ntaub ntawv uas tsuas yog 1-ntsis suav ntawm cov ntaub ntawv
Dab tsi yog qhov txawv ntawm cov neeg siv kev paub thiab kev paub ntawm cov neeg siv khoom?
User Experience (UX) cuam tshuam nrog tib neeg cuam tshuam nrog koj cov khoom thiab cov kev paub uas lawv tau txais los ntawm kev sib cuam tshuam. Customer Experience (CX), incontrast, encompasses tag nrho cov kev sib cuam tshuam ib tug neeg muaj nrog koj hom
Concept Modeling yog dab tsi hauv kev txheeb xyuas kev lag luam?
Tswv yim Modeling. Lub tswv yim qauv yog ib qho kev siv-kev ywj pheej sawv cev ntawm cov npe uas tseem ceeb rau lub koom haum, npe lossis kev lag luam. Cov ntsiab lus nyob rau hauv Lub Tswv Yim Qauv tuaj yeem txuas mus rau ib qho ntawm cov txheej txheem nce lossis cov txheej txheem qis, xws li cov hom phiaj kev lag luam thiab kev muaj peev xwm
Dab tsi yog qhov tseem ceeb ntawm kev siv kev coj ncaj ncees rau cov ntaub ntawv kev ruaj ntseg?
Rau cov kws tshaj lij kev ruaj ntseg cov ntaub ntawv, muaj ob lub hom phiaj tseem ceeb thaum nws los txog rau cov ntaub ntawv tseem ceeb: tiv thaiv nws thiab paub txog nws qhov chaw. Cov koom haum tsis tuaj yeem xav tias cov ntaub ntawv raug cai lossis tau txais los ntawm kev coj ncaj ncees
